end
Ques1:
Suppose thing that non global zone uses only minimum cores at particular time What the other cores will do, Will it shared to global zone?

We have a DB server which is constantly utilised above 95% above.
This is becoming nuisance when the monitoring team frequently calls to check on it. Frankly I do not know what to tweak or even interpret the outputs.
I noticed constant 30 to 60% in wio column of the cpu utilisation.

I've moved a physical server over to VMWare ESXi 5.1 using SCO 6.0 with MP4. For whatever reason, people are occasionally getting kicked out or are closing out their telnet session and it is leaving their processes running. When this happens, the sar %idle drops from 98-95% down to 25-20%. ... (1 Reply)
Hi all,
Been reading a lot of the cpu load and its "analogy of it to car traffic path of expressway"

That table is over 7 GB, bigger than the rest of the DB combined:

cpc_access
cpc_access(3CPC) CPU Performance Counters Library Functions cpc_access(3CPC)NAME
cpc_access - test access CPU performance counters
SYNOPSIS
cc [ flag... ] file... -lcpc [ library... ]
#include <libcpc.h>
int cpc_access(void);
DESCRIPTION
Access to CPU performance counters is possible only on systems where the appropriate hardware exists and is correctly configured. The
cpc_access() function must be used to determine if the hardware exists and is accessible on the platform before any of the interfaces that
use the counters are invoked.
When the hardware is available, access to the per-process counters is always allowed to the process itself, and allowed to other processes
mediated using the existing security mechanisms of /proc.
RETURN VALUES
Upon successful completion, cpc_access() returns 0. Otherwise, it returns -1 and sets errno to indicate the error.
By default, two common errno values are decoded and cause the library to print an error message using its reporting mechanism. See
cpc_seterrfn(3CPC) for a description of how this behavior can be modified.
ERRORS
The cpc_access() function will fail if:
EAGAIN Another process may be sampling system-wide CPU statistics.
ENOSYS CPU performance counters are inaccessible on this machine. This error can occur when the machine supports CPU performance coun-
ters, but some software components are missing. Check to see that all CPU Performance Counter packages have been correctly
installed.

and might be removed in a future release. Applications should use cpc_open(3CPC) instead.
